new and useful Improvements in Repro-- ducers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in reproducers for talking machines and has for a primary object the provision of a device of the above stated character, which is capable of reproducing sounds on different records now on the market and known by the following names, Golumbia, Victor, Pathe and Edison, thereby providing a device for universal use and one that will successfully operate on difi'erent kinds of talking machines that employ tone arms.

Another object of this invention is the provision of a sound box having the usual diaphragm to which different stylus holders are connected and which have the desired type of styli for reproducing the kinds of records mentioned.

I A further object of this invention is the provision of means for connecting the sound box to the tone arm and which will permit adjustment of said sound box to difi'erent angles, or positions for playing the diflerent types of records.

A further object of this invention is the provision of means whereby the sound box may be easily and quickly disassembled when desiring to make repairs or adjustments to the diaphragm or the means that connects the same to the stylus holder. v

A still further object of this invention is the provision of a reproducer of the above stated character, which shall be simple, du rable and efficient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding-of my invention, reference is to be had to the followtion for playing ing described and accompanying drawings,

in which Figure 1 is a side elevation illustrating a reproducer constructed in accordance with my invention and showing the same positioned to play aVictor or Columbia record. 'Flg. 2 is a similar view, illustrating the reproducer positioned to play a Pathe rec or Fig. 3 is a similar view partly in section illustrating the reproducer positioned to play an Edison record.

Fig. 4 is a sectional view illustrating the same,

Fig. 5 is a detail sectional view taken on the line 5--5 of Fig. 3,

Fig. 6 is a fragmentary sectional view illustrating a modified form of means of connecting the diaphragm to the stylus holders.

Referring in detail to the drawing, the numeral 1 indicates as an entirety a reproducer capable of playing or reproducing the sounds from different types of records now on the market and includes a body 2 that has an annular side wall 3 closed at one end by a circular wall 4. The wall at isprovided with a central sound opening 5 surrounded by a collar or flange 6 detachably secured to the outer face of the wall 4 by fasteners 7. A substantially L-shaped tone arm connecting tube 8 has one of its arm portions rotatably mounted within the collar or flange 6 and has formed upon its ends an annular flange 9 that fits within an annular groove 10 formed in said flange or collar 6, thus, it will be seen that the tube 8 is rotatably secured to the body 2 of the reproducer 1. The last named arm portion of the tube 8 is cut away to form a shoulder 11' that rests upon the face of the collar or flange 6 and cooperates with the flange 9 in securing the tubes to the body or sound box 2. The outer face of the collar or flange 6 is provided with spaced sockets 12 to be engaged by a spring pressed ball 13 carried in an 0 set portion 14 formed on the tube 8 for holding the tube against accidental movement or rotation in relation to the sound box or body 2 and the sockets 12 are so arranged to properly hold the sound box or body 2 in posithe different types of records. 1 The other arm portion of the tube 8 is reduced to form a neck 15 which is received tube becoming accidentally detached from the tone arm and further said tone arm is provided with a locking sleeve 17 whereby the frictional contact between said tone arm and tube can be increased to such an extent that the tube 8 cannot be detached from the tone arm until the locking sleeve 17 has been unthreadedor released.

A disk 18 constructed from felt or any other material suitable for the purpose is placed within the body or soundbox 2 and against the wall 4 and isprovided with an opening in alinement with the sound open-- ing 5 and has positioned thereon an annular cushion member 19 constructed from rubber or any other suitable material to support a diaphragm 20. An annular packing member or ring 21 is positioned againstthe diaphragm 20 and held against thesam'e by an annular attaching member or ring 22 which is threaded into the body .or sound box 2 thus it will be seen that the'packing and diaphragm can be easily and quickly removed from the body or sound box 2 for repairs and also can be adjusted therein by the attaching ring or member 22 owing to its threaded engagement with the annularwall 3 of the sound box or body 2.

An attaching member 23 includes right angled flanges that engage the circular wall 3 of the sound box or body 2 and secures thereto a sheet of catgut or similar material 24 for closing the sound box to retain the sound therein. The attaching member 23 is secured to the sound box 'or body 2 by means of a serles of fastening elements 25 that have one of theirends bent to overlie theattahng member 23 and the other end screw threaded and extending through lugs 26 formed on the wall '3 and provided with countersunk openings to receive nuts 27 threaded to said fastening elements 25.

Spaced cars 28 are formed on the wall?) of the body or sound box adjacent one edge of said wall 3 and have pivoted therebetween a double stylus holder 29 by set screws 30 which are provided with lock nuts 31. The stylus holder 29 is capable of adjustment with relation to the sound box or body 2 by the set screws 30 and after being adj usted the set screws 30 are turned against the stylus holder with sufficient tension to hold said stylus holder against accidental move-' thereon and turned against the ears 28. The

double stylus holder 29 includes a body 30 with stylus receiving portions 31 and 32 respectively. The portion 31 is in a plane with the body 30 and is provided with a stylus receiving socket 33 to receive the ordinary stylus 34 used for playing Columrecords.

aseaaee jacent the inner ends of said styll, astylus arm or bar 38 which is curved and extends through an opening 39 in the wall 3 of the body or sound box and, has formed on its inner end a head 40 which engages the diaphragm 20 and is provided with a screw threaded extension 41 that passes through the diaphra m and has threaded therepn a securing e ement 42 which also bears against the diaphragm and coiiperates with the head 40 in firmly securing the stylus arm or bar 38 to, the diaphragm so that the motion of the stylus holder 29 will efliciently effect the diaphragm to produce the desiredv sound. When'the stylus 34 is used to play Columbia or Victor records, the sound box 2 is positioned as illustrated inFi 1 and when the stylus 36 is used to play athe records, the sound box is posi-,

tioned as illustrated in Fig. 2.

A stylus supporting member 43 of substantially V-shape is formed inte rally with the clamping member. 23 and 1s" disposed over the catgut 24 and has spaced ears 44 formed on its apex between which is pivoted astylus holder 45 which is of substantially S-shape, having one end connected to the diaphragm head 40 by a thread or similar element 46 that extends through an opening in the catgut 24 while. the other end of said stylusholder 45 projects between and beyond the arm portions of the stylus supporting member 43 and carries an ordinary stylus 47 used to reproduce Edison records. The stylus holder 45 has formed thereon an ear 48 which is engaged by a leaf spring 49, that is seeured to or formed on the clamping member 23 so that said stylus holder is capable of having pivotal movement on the supporting member 43 and at all times the thread or element 46 s kept under tension. When the stylus 47 1S employedto play Edison records, the

sound box 2 is positionedas' illustrated in.

Figs. 3, 4, and 5 or horizontally over said Referring to Fig. 6 which illustrates a modified form of my invention, the stylus arm or bar 38 terminates after entering the opening '39 and has connected thereto a thread or slmi-lar element 50 whichv is in turn connected to a diaphragm head 51 sehead 51 as clearly shown in Fig. 6.

While I have shown and described the preferred embodiment of my invention, it

will be understood that minor changes in construct on, combinatlon, and arrangement of parts may be made without departing from the spirit and scope ofthe invention as claimed.

Having thus described .my invention, what I claim is 1. A reproducer comprising an annular body having one end partly closed by a wall, a diaphragm in said body, a stylus holder carried by thebody and connected to the diaphragm, a clamping ring on said body, a closure element closing said body and held on the latter by said ring apertured lugs on said body, rods extendlng through the lugs and having angular ends engaging the ring, and fastening means on said rods.

2. A sound I box having a single diaphragm, a stylus holder pivoted to and extending radially from said sound box, a

second stylus holder pivoted to and extending longitudinally from said sound box,

means connecting both of said holders to said diaphragm, and a spring engaging one of said holders.
